El rendimiento de un sistema paralelo depende tanto de la configuración de recursos de la computadora, como del tipo de aplicación a ejecutar. Por ello, el estudio del comportamiento de aplicaciones paralelas en cluste...

In the Laboratory of Research and Development on Computer Science of the National University of La Plata, a face recognition system has been developed. This article describes a series of testings based on parallel proces...

This paper describes two parallel algorithms for the eÆcient processing of relational database transactions and presents a performance analysis of them. These algorithms are built upon the bulk-synchronous parallel mode...

Most parallel applications contain data parallelism and almost all discussion of its solutions has limited to the simplest and least expressive form: flat data parallelism. Several generalization of the flat data paralle...

The design of parallel programs requires fancy solutions that are not present in sequential programming. Thus, a designer of parallel applications is concerned with the problem of ensuring the correct behavior of all the...

Este trabalho estuda as várias formas de integração do paralelismo E e do paralelismo OU na Programação em Lógica. O trabalho engloba os principais sistemas, a saber: ANDORRA-I, ACE, ROPM e IDIOM. Ao final, é feit...

El trabajo presenta la investigación y desarrollo de un entorno que permite el acceso remoto a laboratorios multicluster. El resultado es una capa de software de administración que puede ser accedida mediante una aplic...

Este artigo propõe recursos para o escalonamento de objetos distribuídos. Para tanto, são definidos dois mecanismos tidos como centrais para tal: um primeiro que irá realizar a instanciação remota de objetos Java, ...

This work presents the authors investigation regarding the application of parallel processing to the design of grounding systems, comprising concrete encased electrodes. The natural parallelism of the involved tasks and ...

In several applications, the trajectory of an entity, a feature or an object has to be tracked over a sequence of image frames. When the processing is to be performed in real time, there are important constraints leading...

In this paper we explore different situations in which collaborative agents have to communicate among themselves using standard interaction protocols. We will propose how to process these interactions in parallel without...

Data parallelislm is one of the more successful efforts to introduce explicit parallelism to high level programming languages. This approach is taken because many useful computations can be framed in term of a set of ind...

Allocation of the components (tasks) of a parallel program to processors in a multiprocessor or a multicomputer system take full advantage of the computational power provided by the system. Evolutionary approaches has b...

The problem of how to find a schedule on m > 2 processors of equal capacity that minimises the whole processing time of independent tasks has been shown as belonging to the NP-complete class (Horowitz and Sahni [12]). Ev...

A solution of problems in multiagent systems involves representing beliefs of agents immersed in dynamic environments. Observation-based Defeasible Logic Programming (ODeLP) is an argument-based logic programming languag...

Este trabalho apresenta a integração dos modelos ParTy e Granlog. O ParTy (Parallel Types Analyzer) é um interpretador abstrato de tipos. O Granlog (Granularity Analyzer for LOGic programming) é um analisador automá...

A tecnologia de cluster, impulsionada pelo advento de redes de alta velocidade, tem se tornado um importante veículo na otimização de aplicações potencialmente paralelizáveis. Existem diversas formas de melhorar o ...

Este artigo apresenta um estudo sobre a aplicação da análise de complexidade na paralelização de programas em lógica. Inicialmente, o texto descreve a estrutura do módulo Analisador de Complexidade proposto pelo m...

Es creciente el número de algoritmos de cómputo científico que corren con mayor eficiencia en las placas procesadoras de video (GPGPU - General Programming Graphics Processors Units) que en los propios procesadores mu...

When IBM's John Backus first developed the Fortran programming language, back in 1957, he certainly never dreamt that it would become a world-wide success and still be going strong many years later. Given the oft-repeate...

This article describes strategies devised to improve the efficiency of two classical index data structures for parallel textual databases. The design and cost evaluation is effected on top of the bulk-synchronous model o...

Audio identification consist in the ability to pair audio signals of the same perceptual nature. In other words, the aim is to be able to compare an audio signal with a modified versions perceptually equivalent. To accom...
